build: Move the compiler checks and libtool initialization up

Browse Source 
It seems logical to first look for the compiler and then run the rest of
configure script (which will use the compiler with small snippets).

Same goes for the libtool initializaton, you might as well do it not too
far from the automake one.

This also happens to be preparatory work to compile cogl with an in-tree
copy of some glib files as the glib's configure script needs those
checks early.
